Usage

The most comomon use cases for this tool are:-

  • Generating a seed
  • Generating seeds via dice rolls or playing cards
  • Generating BIP85 child seeds (or check those generated by a hardware wallet)
  • Generating BIP47 payment codes and corresponding PayNym
  • Verifying wallet address generation from a given seed/passphrase combination
  • Verifying wallet entopy inputs (dice rolls or card picks)
  • Testing for a forgotten/incorrect passphrase (if you know a receive address)

  • 🤖 Generate a cryptographically strong random mnemonic
  • 🎲 Enter in your own entropy
